Your Role And Responsibilities

We are seeking a highly skilled Physical Design Engineer with advanced expertise in static timing analysis using Cadence Tempus. The ideal candidate will take ownership of timing closure across multiple blocks and top-level designs, partnering closely with synthesis, PD, and signoff teams to deliver high-performance, low-power SoC designs. KEY RESPONSIBILITIES: Lead timing closure strategy for full-chip / hierarchical SoC designs using ILM/ETM-based flows Own signoff correlation between Tempus and other tools (PrimeTime, Innovus, etc.) Drive timing closure across all PVT corners and MMMC modes; debug and resolve timing violations Define and enforce timing methodology guidelines across the team; mentor junior/mid-level engineers Develop and validate SDC constraints; perform timing ECOs (buffering, resizing, logic restructuring) Drive automation – develop reusable TCL/Python scripts for timing analysis, reporting, and waiver management Analyze SI, crosstalk, and noise issues; handle Tempus SI for crosstalk delta-delay and glitch analysis Interface with Cadence EDA vendor for tool issues and new feature adoption Participate in architecture and floorplan reviews to identify timing risks early Contribute to DFM and low-power (CPF/UPF) timing signoff; generate timing reports and signoff closure
